Stan's NoTubes Tubeless Valve Stem Pair

Although tubeless set ups remove tubes entirely from the equation, you'll still need valve stems to seal the rimtire interface from losing air, as well as provide a method for tire inflation and sealant injection. That's where Stan's NoTubes Tubeless Valve Stem Pair comes into play. These 44 millimeter valve stems feature a removable valve core for injecting sealant into your tubeless set up without dealing with the hassle of breaking your tire's bead. You'll find they work equally well with UST, Road Tubeless, and standard tube type rims, thanks to their universal shape and rubber cone along the end opposite of the valve.
